Homectrl v2: common questions
What microcontroller does the Homectrl v2 use?
The Homectrl v2 is built around the ESP32-S3-WROOM-1, from the ESP32 family.
How big is the Homectrl v2 PCB?
The Homectrl v2 measures 64 × 70.5 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Homectrl v2?
127 components, from 64 distinct parts. The full bill of materials is listed on this page.
Where can I download the Homectrl v2 design files?
From the jeevan9s/homectrl-sys repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Homectrl v2 design in my own project?
The repository has no license, so all rights stay with jeevan9s. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Homectrl v2 without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
